To cll'whom it may concern: l

Be it known that l, GEORGE l Cuisine, J r.,

a citizen off-the United States, residing at Pittsburgh,`1 Allegheny county, and State of Pennsylvania, have invented and discovered certain -new and useful llmprovements in Processes of Preparing- Ethylene Dichlorid from Ethylene, of whlch the'following is a specification.

As 1s Well ethylenedichlorid from ethylene, it is only necessary to bring the ethylene and chlorin together; under almost any conditions a reaction vproceeds as per theequation @,H, -I- CIZf-MZHL.

`vents applied-at once. 'llhe ethylene can .be

liquefied in asimilar manner.

My present invention consists, therefore, inthe process forrpreparing ethylenedichlorid by the chemical union of ethylene and chlorin which are both in the' liquid conl ditionthis application being a division of my application No. 101,637.

he accompanying drawing, which is made a part hereof, illustrates an apparatus such as has been found appropriate for the practice of said process, although the successful application of the process is not dependent on using this' 'exact apparatus and must be varied as liquid ethylene is added to the 1i uid chlorin, or vice versa, or both added simultaneously, as hereafter described.

`rll`h'e said a Aparatus consistsof a vessel 10,With an in et pipe 11 for liquid ethylene `and an inlet pipe 1.2 for the liquid, chlorin,

known, in ordeil to prepare `together in the proper proportions.

leading into the upper portion of said vessel, and an outletfpipe 131 with a valve 1,4, leading from the bottom' of said vessel. An ethylene supply tank 15, compressor 16, a chlorin suI ply,-`comprising a' battery .of

:cylinders 1 a compressor 18, and condenser coils 19 and 2 0 forthe ethylene and'chlorin, pipes, respectively,

complete the apparatus. `It will be un rstood that this merely illustrates an arrangement such Vas has been vfound practicable, butmay be varied in any appropriate manner, for example, -the process easily lends itself to. an arrangement for continuous operation.

'The operation here given consists in liquefying bothethylene and chlorin at a pressure greater than the vapor pressure exerted by the ethylene-in the vessel 10 atl the temperature used, and bringing the two This, then, permits of a complete and rapid union of the ethylene and the'chlorinimmediately upon mixing ofthe two liquids.I giving pure ethylenedichlorid. yThe ethylene and'chlo. rin are y continuously added in molecularly equivalent quantities. If both substances are pure, no' residue other than pure ethylenedi- 'chlorid remains; the pure ethylenedichlorid,

a liquid, is drawnolj' through outlet pipe 13 controlled by valve 14:'.

Naturally, as soon as the vprocess has proceeded a short time,- the liquid content of vessel 10 contains both liquid chlorin, liquid ethylene,.an d ethylenedichlorid, which are mutually soluble in each other. This gives the same result as though a mixture oiv ethylenedichlorid and liquid chlorin (or -ethylenedichlorid and ethylene) were used at the start, and. indeed; such may be done with` equally good results, or an inert liquid,

mixed with the'liquid chlorin (or liquid ethylene) may be'. used which later fczn be separated from the' ethylenedichlorid.

Having thus fully described m said in-Irl vention, what l clalm as newan desire to secure by Letters Patent` is:

The process of producing ethylenedi- @merid which 4consists, in combining ethylene and chlorin both in liquid condition, suhmy hand :md seal at Washington, District stantially as set forth, of Columbia, this sixth day of September :2.
